 bands, grayish or yellowish-buff. Below, bright lemon-yellow, brighter than 

 in previous dress, throat lores and auriculars ashy-gray. 



4. FIRST NUPTIAL PLUMAGE acquired by wear, which is quite 

 obvious, the edgings of the wing coverts and tertiaries fading to 

 a dingy white and the whole plumage becoming paler.

 nuptial moult beginning early in August and completed before 

 the birds move south in September. Practically indistinguish-

 plumage, wing coverts and tertiaries, but not the rest of the 

 wings nor the tail. Birds in Juvenal dress occur as late as the
